# OpenText Directory Services (OTDS) 22.1 to 26.2: observable discrepancy flaw (black box reverse engineering)

OpenText lists CVE-2026-19134 in Directory Services (OTDS) 22.1 to 26.2 as 'black box reverse engineering', weakness CWE-203 (observable discrepancy). CVSS 4.0 is 7.1: network, low complexity, low privileges, high confidentiality impact. OpenText's full advisory is behind a support login, so the exact leak is not public. No exploitation or PoC is known.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:OpenText Directory Services (OTDS) affected >= 22.1, <= 26.2 (before the patched build of each branch) fixed 22.4.21, 23.1.10, 23.2.8, 23.3.11, 23.4.20, 24.2.8, 24.3.7, 24.4.22, 25.1.12, 25.2.11, 25.3.13, 25.4.11, 26.1.8, 26.2.5

## How to check

Find your OTDS version (admin console or installer record). Affected: 22.1 through 26.2 unless you are on a patched build for your branch: 22.4.21, 23.1.10, 23.2.8, 23.3.11, 23.4.20, 24.2.8, 24.3.7, 24.4.22, 25.1.12, 25.2.11, 25.3.13, 25.4.11, 26.1.8, 26.2.5 or later (from CNA data via OpenCVE; confirm in OpenText KB0876890 with a support login).

## Fix

Upgrade OTDS to the patched build for your branch: 22.4.21, 23.1.10, 23.2.8, 23.3.11, 23.4.20, 24.2.8, 24.3.7, 24.4.22, 25.1.12, 25.2.11, 25.3.13, 25.4.11, 26.1.8 or 26.2.5 (secondhand, not read on OpenText's page).

- 2026-11-05T20:44:56+00:00 analyst https://app.opencve.io/cve/CVE-2026-19134 — Vendor KB cited by CVE (KB0876890) is login-walled and its public header is for a different CVE (CVE-2026-76580, XSS), so no primary text for 19134 read. OpenCVE shows OpenText CNA data: CWE-203 (observable discrepancy), CVSS4 7.1 AV:N/PR:L/VC:H, patched builds per branch. Nothing verified; no exploitation or PoC found.
